The function named myRandomNum that returns a random integer in the range [1, 100] is defined as follows: int myRandomNum () { return rand()%100 + 1; } Now, write a program (code fragment) that repeatedly generates and prints random integers in the range [1, 100]. The program must stop when the absolute value of the difference between successive printed values is less than 5. Two sample output is given to help you understand the problem: 1. The program can possibly output this: 76 43 77 94 54 66 64 2. The program can possibly output this: 42 45 Note: 1) The srand statement has already been provided for you (see below). 2) You must use the given function myRandomNum to generate random integers.

Answer #1

Raw_code:

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

// myRandomNum() function
int myRandomNum(){
return rand()%100 + 1;
}

// main() function
int main(){
// srand function with time(NULL) as parameter
srand((unsigned)time(NULL));
// initializing two variable with random numbers by calling myRandomNum() function
int num1 = myRandomNum();
int num2 = myRandomNum();
// variable for storing absolute difference of both random numbers,
// initialized with absolute difference of num1 and num2
int diff = abs(num1-num2);
// printing both the random numbers
printf("%d\t%d\t", num1, num2);

// while loop runs until the diff is lesser than 5
while(diff >= 5){
// assingning num2 to num1
num1 = num2;
// generating new random number and assingning to num2
num2 = myRandomNum();
// calculating the absolute difference
diff = abs(num1-num2);
// printing the random number generating during this iteration
printf("%d\t", num2);
}
}

// you can change srand statement and 8 different ouputs have been placed

Write a function int count_consonants(char str[]) that determines and returns the number of consonants in a given string. Then write a simple main() function where you can repeatedly enter a string and then the num- ber of consonants is determined and printed on the screen (from the main() function). If the entered string is empty (it will contain only a ’\n’ then) the program should stop its execution. You can safely assume that the entered string will be not longer...

There are N blocks, numbered from 0 to N-1, arranged in a row. A couple of frogs were sitting together on one block when they had a terrible quarrel. Now they want to jump away from one another so that the distance between them will be as large as possible. The distance between blocks numbered J and K, where JK, is computed as K-J+1. The frogs can only jump up, meaning that they can move from one block to another...
